So a couple of years ago, Cameron asked parliament for support in kicking Assad out. Now he wants support for kicking opposition to Assad. (Throwing in with Russia is tantamount to exactly that.)

No wonder those politicians who think before they vote are between a rock and a hard place. Military intelligence cannot be trusted to help form a view and the only certainty is that this isn't a leadership cult. You can kill every leader and cell in ISIS and it will take all of a couple of years to get them replaced by the ideology that you can't fight with toy soldiers. In fact, bombing them merely acts as a recruiting sergeant for the next lot. Plenty of fertile hiring fairs around too, after the West's interference to date in Middle East and Africa.

Me? I'd turn the tap off to Saudi Arabia. We speak of the intelligence they give us to help crush extremists but ignore their promotion of the cancer it is spawned from.

They use their right and left hands for different purposes if you hadn't noticed.
